ROLLER-BEARING.

To allwhom it may concern:

I 3e it known that I, JonNE. PARRISH, a citizen of the United States of America, and

resident of Springfield, in the county of llampden and State of Massachusetts, have invented certain new and useful Improve ments in Roller-Bearings, of which the following 1s a full, clear,"and exact description.

This invention relates to improvements in roller bearings of the class in which rollers in sidewise separated relations are provided between an outer annularor cylindrically chambererl member and an inner member of cylindrical form with a secondaryser'ies of rollers in peripheral contact between suitable portions of the rimary rollers for preventing what is sometlmes termed cross friction or sliding or wipin *surface contacts of the primary rollers w 'ch are between the inner and outer members of the bearings, one on another. I

The principal object of this invention is to provide const uctions and arrangements of parts including rimary and secondary series of rollers where y not only cross friction is avoided between the rollers, but whereby there is practically no sliding or wi ing movemcnts of any of the interengagecl parts one on another. Another object is to produce the roller hearing device, having advantages above re-' 'i'erred to, of extreme simplicity of construction and practicability of assemblage.

(it-her objects are attained in and by constructions, combinations, and arrangements of parts which constitute this invention as hereinafter described in conjunction with the accompanying drawings and as set forth in the claims.

In the drawings Figure 1 is an end face view of the roller bearing device; Figs. 2 and 3 are sectional views on the plane of the axis as variously taken on the lines 2-2 and li it, Fig. 1 Fig. 4 is a sectional view of parts represented in Fig. 2, but. showing some of them as in slightly changed relations; Fig. 5

In the drawings,- A represents an outer annularor cylindrically chambered member Within which the bearm is inclosed, and B represents a cylindrica member concentrically within the one A; and the same may be solid or made with a central aperture whereby it may be applied as a bushing to fit and be aflixed to a shaft or arbor.

C C represent a series of sidewise separated )rimary rollers, between, and peripherally hearing on, the surfaces of the outer annular and inner cylindrical members A and B; and

these rollers have axialend extensions ct of reduced diameter. D 1) represent shorter rollers or trucks of a secondary series comprising axially alinedcylindrical heads 10, 10 and head uniting "necks 12,, as shown. by these'reference numerals on Fig. 3, said heads 'bein arranged between'and having peripheral earings on the reduced end extension a of the primary rollers, and maintaining them in their sidewise separated arrangements.

E and F represent edgewise separated and concentric rings both in the same, plane transversely of the axis of the device and having their adjacentmargins overlapped within the inner faces of the opposite heads of the rollers of the secondary series; and within the annular space between said rings through and outwardly beyond which space the said reduced extensions a of the primary rollers project.

A lurality of centrally apertured disks 7) are a nod by having hard driving fit onseveral of the reduced. roller extensions, sald disks having their inner faces beveled from i their periphery toward their axis, or made in the form of a cone or conoid; and said disks constituting shoulders on the primary roller.

extension a have overlapping relations relatively to the adjacent marginal outer sill faces of the rollers D, and by reason of, their beveled or conical formations, have,- in the action of the bearing wherein they rotate on 1 their individual axes and also have planetary movement, not frictional sliding or wiping contacts on the roller ends, but rolling contact thereon.

The primary rollers have comparatively deep grooves between their ends, engaged in WlllGh are ribs constituted by rings and g detachably fitted and secured, with t eir locations in a coincident lane, the one within the annular outer mem er A and the other ing engagements, thereby obviating face fric on the eri hery of the cylindrical member B,-suo n and groove engagement pre venting endwise displacement ofthe primary rollers. The rings E and F maintain the secondary rol em or trucks always in the same plane and collectively a ainst endwise displacement or lash relatlvely to the rings themselves and the disks 1) restrain the rings, and the therewith interlocked rollers D from having an axial movement. The rings, moreover, 'eingalways'maintained in their concentric relations, one to another, and both to the axis of the bearing as a whole, correspondingly keep the series of secondary rollers or trucks to their bearings on the primary roller extensions 0 at all places around the bearin i The inner faces of the heads 10, 10, of the secondary rollers D are beveled and relatively convergent toward the head-uniting necks as indicated at 17 in Figs. 3 and 6; and 'it' is by these beveled portions of such rollers that the rolling bearings between the latter and the corners of the rings are acquired, thus obviating the possibility of friction between the inner surfaces of the roller head and the inner and outer faces of the rings. The aforementioned ribs' and g of the inner and outer members A an B of thedevice are also made with beveled sides on which the corner edges of'the' primary rollers C C have rolling beartion at these places of line contact,it-being here mentioned that there will be little liabilit of-the last mentioned parts of the bearing ecoming cut or worn because of the absence of any cause of end thrust, as all pres-' sures to which the'bearing is subjected are in a direction across, and not along the line of, the axis. 1

' This bearing, the parts of whichare in compact and interengaged relations as shown, requires for the assemblage of such parts the exercise of a considerable degree of ingenuity; and the construction and relative arrangements of some of the parts making for practicability of assemblage will be now pointed out.

The member Bhas between its ends a plurality of radial sockets 18Which open to 'its periphery, and it also has holes 19 arallel with its axis leading from end to en of the member B and intersecting said sockets. Pieces 20 shown as having the form ofcylin ders or small plugs with conical ends are movably fitted in said sockets.

The rib forming ring 9 which has a close sliding fit circumferentially onv the bearing memberB is preferably internally recessed, as by havinga continuous annular roove 22 therein. Pins 23 constructed wit necked down tapered portions 24 have driving fits in said holes -19, and by their tapered portions engage the inner ends of the little plugs or pieces 20 and outwardly force them to their engagements by their outer conical ends in the internal groove of the rib-forming ring.

The rib forming grooveffor the outer annu-' lar member A of the bearing is peripherally grooved'and when slid to its proper intermediate position is retained by the engagement in its groove 2I by the conical end of the screw plug 25, this form ofengagement being pluralized in a desirable degree as apparent in the drawings. The rollers C O and the rib forming rings f and g are interengaged and then slid to place in the annular ppace between the bearingmembers A and and the confinement of the 'ribforming rings is then effected by the means above described.

The partial sectionalview, Fig. 4,'shows how byforcing the pin'23 a short distance 'endwise, its tapered or cam like portion 24 is positioned to ermit the confining piece or plug 28 to recede inwardly from its engagement with the rib forming ring g so that. the latter may be slid-off from, or up to, the position which it is re iiired to occupy in the properly assembleddevice,

I will -now describe the specific means here provided for adjusting the rings F and E to, and maintaining them in, their concentric positions, reference being had to Figs. 2 and 3. ,The inner cylindrical member B has cylindrical hub-like end extensions i of reduced diameter made with sockets 30 opening to their peripheries and having holes 32 leading from their ends and intersecting said sockets; Pieces which advantageously may be com ose of hardened fiber and. having rounded or-conical outer endsfare movably fitted in the socket. 30, and

screws m made with conical ends have thread engagements in the holes 32 and exert camlike and outwardly forcin actions against the pieces 7' for adjusting an maintaining them in their. engagement with the inner edge of the inner one F of the-rings. being held in its properosition will control the position, concentrica ly'therewith, of the o'utp; ring E through the medium of the rollers.

' I n;the operation of the roller bearing device, assuming that one of the members, either the outer one A or the inner one B, is stationary and the other is revolved, the action of the revolving one will cause rolling and planetary movements of the primary rollers C, and the secondary rollers D which have planetary movements concurrently With'the primary rollers have, individually, rotations 1n directions the reverse of the directions of rotations of the rimary rollers and the rings E and F which form circular tracks around which the secondary rollers have running engagements, incidentally, partake of turning movements as im arted to them by the rotating and also revo ving secondary rollers,ithe outer ring moving con- The inner ring,

siderably slower than the inner one by reason ofthe rollers G having to operate .on greater circumferential surface.
